The house price to income ratio is the ratio of the cost of a typical upscale housing unit of 100 square metres, compared to the countrys GDP per capita. Normally this ratio will be much higher in low income countries than in high income countries.

The formula is: (Price per square metre / GDP per capita)*100. The house price to income ratios published by the Global Property Guide are based on the Global Property Guides own proprietary in-house research, but we use the IMFs GDP per capita figures.

The United Kingdom (UK) has monthly and quarterly house price time-series.
The Land Registry has a monthly house price index. Nationwide, and the Halifax, and many other commercial organizations publish quality UK house price time-series.
Construction activity is published by Office for National Statistics (ONS) and property transactions data by the Council of Mortgage Lenders (CML).

The rents situation is much less good, the only figures being from the Association of Registered Letting Agents (ARLA).
